Title: Coordinate input device
Inventor: MORI YOSHIHIRO
IPC: G06F3/03
Filed: 1985-04-22
Abstract: PURPOSE:To input coordinates which are easy to use and have a high accuracy, by constituting a device so that the arithmetic of coordinates is started when the sum of outputs of load detectors exceeds a preliminarily determined minimum value and becomes maximum. CONSTITUTION:A maximum detecting part 9 outputs logical '1' when an output F of an adder 6 is maximum. A comparator 10 outputs logical '1' when the output F exceeds a prescribed maximum value for a reference voltage Vref1. A comparator 12 outputs logical '1' when the output F exceeds a prescribed minimum value for a reference voltage Vref2. Consequently, an AND circuit 13 outputs logical '1' when either of the detector 9 and the comparator 10 and the comparator 12 output logical '1'. A signal switch 2 is switched to subject outputs of load detectors to A/D conversion in an A/D converter 3 in order from the output of a load detector 1a, and corresponding outputs of storage devices 4a-4d are subtracted in time division by a subtractor 5 to obtain outputs f1-f4 proportional to loads. Outputs f1-f4 are added by the adder 6 to obtain the output F. Thus, coordinates are operated and outputted from a coordinate computing element 7 if the output of the circuit 13 is logical '1'.

Abstract: PURPOSE: To improve electrical connection between a base plate and an ohmic electrode by opening a contact hole after completion of formation of a non-dope multi-crystal silicon thin film on a silicon dispersion layer.  
     CONSTITUTION: After completion of formation of a silicon dispersion layer 3, formation of a non-dope multi-crystal silicon thin film 7 is started immediately. A thick silicon oxide film 4 is formed, and a contact hole 5 is opened to be used as an electrode take-out hole. When boring the contact hole 5, etching liquid is not brougt in contact directly with a silicon dispersion layer 3 and a silicon oxide film 2 because of presence of the multi-crystal silicon thin film 7. And therefore, it is possible to prevent formation of a stain film on the surface of the silicon dispersion layer 3. An aluminum soldered layer is formed, and aluminum wirings 6 and 6' are formed by photographic etching.

A second ion beam B11 is radiated to a current detector 38 via the slit of the selector unit 27, and then, a measuring unit measures a current value according to desired ions on the basis of the beam B11. Strength of the magnetic field generated inside the separator 26 and the width of the slit of the selector unit 27 are set based on the measurement result. In this state, the desired ions are implanted into a wafer.

Title: Display integrated type tablet device
Inventor: TAGAWA KOSEI
IPC: G06F3/0488
Filed: 1993-04-13
Abstract: PURPOSE:To stably and accurately detect the tip coordinates of a detection pen even if a noise due to the frictional electrostatic charging of the detection pen is detected during a coordinate detection period. CONSTITUTION:A coordinate detecting circuit internally has a comparator which converts the induced voltage signal from the detection electrode of the detection pen into a binary signal. The tip dielectric of the detection pen and the input panel of a liquid crystal panel use such a pair of materials that the polarity of the frictional electrostatic charging of the tip dielectric is the same as the polarity of the slice voltage 'e3' of the comparator. Thus, the polarity (plus) of a misdetection signal induced at the detection electrode owing to the discharging of the frictional electrostatic charging is made opposite from the polarity (minus) of the slice voltage 'e3' to remove a misdetection signal component mixed with the induced voltage signal from the detection electrode. Consequently, even when the noise due to the frictional electrostatic charging of the detection pen is detected, the tip coordinates of the detection pen can stably and accurately be detected.

Filed: 1994-04-25
Abstract: PURPOSE:To obtain a recorder by which image is recorded through selective forming of plural dots by toner and the toner save recording is executed properly without troublesome manual operation by a user. CONSTITUTION:Since the toner save recording or the non-toner save recording is selected automatically depending on toner save relation information such as toner residual amount by the execution of a toner save flag setting program, manual operation of a selector switch of the user to select either of them is not required. Furthermore, when the toner save recording is selected, the recording section is controlled based on toner save image data and the consumption of toner is less than that based on the original image data. Then the original image is recognized from the recording image formed based on the toner save image data.

Title: Lockup type automatic transmission gear
Inventor: KIYOSHIGE SATOSHI
IPC: F16H61/14
Filed: 1982-05-21
Abstract: PURPOSE:To prevent the occurrence of any shift shock, by preventing a torque converter from being brought into a lockup state while the temperature of a working oil for an automatic transmission gear is below a given value. CONSTITUTION:An AND gate 228 is caused to output an L level signal without fail so that a thermo switch 74 brings a working oil signal ST down to L level when the temperature of a working oil for an automatic transmission gear is low. In this case, even if a lockup permission signal SL of H level is supplied to the AND gate 228, a lockup solenoid 31 is not energized, and a torque converter can be prevented from being brought in a lockup state. Thus, under a condition in which a shift shock is apt to occur, the shift shock is absorbed by the torque converter held in a converter state, and this permits the shift shock to be prevented from being propagated to a car body as it is and promotes the improvement of a riding comfortableness.

Abstract: PURPOSE:To reduce greatly the return distortion of a luminance and a color signal generated owing to the spatial sampling of a photosensitive part which is spatially discrete and to obtain a reproduced color image of high quality by changing directions of optical band limitation and obtaining square-law characteristics of the cosine of the return distortion. CONSTITUTION:A direction shown by dotted lines is an optical band limitation direction; and conventional optical band limitation crossing space frequency positions (0, + or -1/2Py) and (+ or -1/2Px, 0) is not performed and band limitation on diamond-shaped lines connecting (0, + or -1/2Px, + or -1/4Py) and (+ or -1/Px, 0) is carried out. Band limitation characteristics of a conventional filter are compared with those of this invention and then characteristics of respective band-limiting filters in directions of axes Wy, Ws, and Wx are as shown by dotted lines in figures (a), (b), and (c). Solid lines indicate characteristics of a conventional example. A return distortion component almost at a zero-beat point is suppressed greatly with cosine square-law characteristics. Zero beats generated at the position (1/2Px, 0) have almost no variation inside of the position, but have the peak reduced almost to half outside of it with the cosine square-law characteristics.
